Hi everyone,I'm new to the forum.

I need help big time and i hope you'll know what my problem is so iam gonna tell you exactly what happened. OK so I was driving my camaro home from work (its a 95 z28 auto) and I was having a little fun with the car. I pressed on the gas just to burn some rubber and then I hear a noise in the exhaust (Kind of like a small backfire) so I let off the gasand drive home. when Im entering the driveway the car was shaking( like if the motor wanted to die). so now, when I turn the car on it wont start If i dont give it a little gas, when it finally starts it blows a puff of smoke through the exhaust, and no its not oil burning. its like fuel vapor because you only see it at the tips and it doesn't go up, it dissapears, like vapor. and it smells a lotlike fuel. also the exhaust sounds different, it doesnt have that low rumble anymore, (sound like a bent valve)when the car is running the engine shakes like a missfire or something.So can anyone help me with mydilema. I miss driving my car

I alredy changed the spark plugs and wires and it still the same.

 

did you check the feul pressure or feul pump...?

 

You broke your car, and now it is misfiring. May have bent a valve, as you mentioned, or blew a head gasket. In any case, do a compression test to verify there is a bad cylinder. If there is one or more bad cylinders the head/s will have to come off, regardless of what caused the problem. If the compression test is good, then the engine should be sound, and you can start looking for the usual problems, like ignition and fuel delivery.

 

thanks for your help guys, i already did a compression check and 2 pistons were bad. I am rebuilding the heads now, can't wait till the car is redy to roll. i miss the exhaust rumble.

sorry I took too long to answer,I was out of town
